A few minutes earlier, a single had buzzed quickly past Reynolds, and standing there on the mound, Drew thought his teammate looked "glazed over."

When other Diamondbacks infielders brought it to their manager's attention on the mound, Kirk Gibson glanced at Reynolds and reached the same conclusion.

"I looked at him, and it was obvious something was going on," Gibson said after the Diamondbacks lost 7-2 to the Washington Nationals at Chase Field. "We had to get him out of there for sure."

Reynolds, who was not available for comment, was evaluated by a team doctor and is considered day to day, Assistant General Manager Peter Woodfork said.

"It was precautionary," Woodfork said. "As we moved on in the game, he didn't feel 100 percent right. It'll be day to day. I don't think it's anything to worry about right now."

Reynolds, who throughout his four-year career has a reputation for playing through just about any injury, mentioned during the pitching change that he felt dizzy, second baseman Kelly Johnson said.

"We know Mark pretty well," Johnson said. "He's going to play through just about anything. If he finally comes over and says something like that, he's not messing around."

His teammates clearly were concerned.

"I looked at him and was like, 'What in the world? Get out of here,' " Drew said. "You don't play around with that stuff."

It was a rough night for the Diamondbacks even before Reynolds' departure. Right-hander Ian Kennedy had an uneven outing, giving up four runs in four innings. Three of the runs scored on a pair of home runs by Nationals slugger Adam Dunn.

Then there was the crowd of 15,670, the smallest in Chase Field history. The previous low was 16,664, set July 8 vs. Florida.

Kennedy struck out the first two batters of the game before falling behind 3-0 to each of the next two hitters, Ryan Zimmerman and Dunn.

Both wound up clobbering 3-1 pitches - Zimmerman for a ground-rule double to left field, Dunn a towering, two-run home run that somehow managed to negotiate the foul pole in right field.

"Two missed spots cost me three runs," Kennedy said of the Dunn home runs. "Giving up four runs and going four innings is not doing my job."

Gibson said he thought Kennedy might have been upset with him for removing him from the game after just 69 pitches. Kennedy said he's more upset with himself for not pitching better.

"It was earlier than normal today, but I also didn't do as well as I normally have," he said. "I'm not happy with myself. I know it's a short leash and my innings are limited, but that's baseball for you."

Rewind

Drew gets spiked: Diamondbacks shortstop Stephen Drew had his left wrist wrapped with ice after the game, the result of a hard, feet-first slide by Mike Morse in the third inning.

During a steal attempt, Drew caught a throw from catcher Miguel Montero and, in applying the tag, was cut by Morse's cleats.

"I knew I was going to get hit, but didn't know where," Drew said.

He was left with three gashes on his arm and said he had trouble getting feeling back in his wrist.

"I felt like I had a 50-pound glove on for two or three innings," he said.

Loss for words: Second baseman Kelly Johnson couldn't explain why the Diamondbacks didn't have more success against Nationals starter Craig Stammen, who gave up just one run in 5 1/3 innings.

"It seemed like we should have looked up and had a few more runs than that," Johnson said. "We didn't. I don't know why.

"He throws a lot of strikes and mixes his pitches. I think we had some balls hit pretty decent at times but we . . . just needed to string them together."

Bad night: Manager Kirk Gibson wouldn't go into specifics, but he thought he made some tactical mistakes during the game.

"I don't think I had a particularly good game myself tonight," he said. "I made some mistakes. I wasn't really on top of it. Chalk it up. It's humbling."

View from the press box

It was pretty sad to see the ballpark as empty as it was. The buzzing of the bullpen phone has never seemed louder, you could practically hear conversations in the stands, and at one point in the late innings, there was a loud crash that seemed to come from left field. For all we know, somebody dropped trays at Friday's Front Row. Gee, you think the Diamondbacks are disappointed they missed out on the attendance bump from a Stephen Strasburg start?
